    Abstract: Techniques for efficient roaming of clients between access points (APs) of a wireless data communications network are described. A first AP receives a request for a first client device to join the network. The request specifies at least a unique identifier for the first client device. An identifier for a second AP is identified by processing the unique identifier using a predefined hash function. The second AP is one of at least two APs configured to each redundantly store network state information relating to the first client device. A network address of the second AP is determined. A first request to is transmitted to the network address, for network state information including a pairwise master key (PMK) and profile information. The PMK and the profile information are received. The first client device is authenticated and a connection is established between the first client device and the network.

    Abstract: Techniques for efficient roaming of clients between access points (APs) of a wireless data communications network are described. A first AP can receive a request for the first client to join the network. The request can specify a unique identifier for the first client. An identifier for a second AP can be determined by processing the unique identifier for the first client using a predefined hash function. A network address of the second AP can be determined using the determined identifier for the second AP. The first AP can transmit a request to the determined network address of the second AP to query for network state information corresponding to the first client, and upon receiving a pairwise master key (PMK) associated with the first client, can authenticate the first client to join the network.
